System, method, and computer program product for updating an application programming interface field of a transaction message

ABSTRACT

Methods for updating an application programming interface (API) field of a transaction message may include receiving, with at least one processor, a payment transaction message, wherein the payment transaction message comprises data associated with a payment transaction; determining, with at least one processor, one or more API fields of the payment transaction message based on the data associated with the payment transaction; and modifying, with at least one processor, one or more API fields of the payment transaction message. Methods may also include transmitting, with at least one processor, a modified payment transaction message based on modifying the one or more API fields of the payment transaction message. Systems and computer program products are also disclosed.

BACKGROUND 1. Field

This disclosure relates generally to transaction processing and, in some non-limiting embodiments or aspects, to systems, methods, and computer program products for updating an application programming interface (API) field of a payment transaction message.

2. Technical Considerations

After a payment transaction is initiated (e.g., at a point-of-sale (POS) terminal or an automated teller machine (ATM)), a message may be generated that is communicated across an electronic payment processing network. This message may conform to one or more message standards (e.g., International Organization for Standards (ISO) 8583 and/or the like). By conforming the message to the message standards, one or more systems that receive the message may accurately identify values associated with transaction parameters of the payment transaction and process the payment transaction. However, in some cases, systems may be configured to process messages generated in accordance with different standards. As a result, systems receiving messages that do not conform to a standard they are configured to process may forego processing such payment transactions. This, in turn, may result in additional communication between one or more systems included in the payment processing network as the payment transaction is re-initiated in an attempt to process the payment transaction.

By virtue of this re-initiation, additional computing resources within the electronic payment processing network may need to be allocated and/or reserved for payment transactions that cannot be processed by virtue of their non-conformity with the standard by which the receiving system is configured to process messages associated with payment transactions. This, in turn, may lead to the unnecessary expense of computing resources and, in some cases, delaying subsequent payment transactions from being processed.

Referring now to FIG. 3 , FIG. 3 is a flowchart of a non-limiting aspect or embodiment of process 300 for updating an API field of a transaction message. In some non-limiting embodiments or aspects, one or more of the functions described with respect to process 300 may be performed (e.g., completely, partially, etc.) by transaction service provider system 110. In some non-limiting embodiments or aspects, one or more of the steps of process 300 may be performed (e.g., completely, partially, and/or the like) by another device or a group of devices separate from and/or including transaction service provider system 110, such as user device 102, merchant system 104, payment gateway system 106, acquirer system 108, and/or issuer system 112.

As shown in FIG. 3 , at step 302, process 300 may include receiving a payment transaction message. For example, payment gateway system 106 may receive a payment transaction message including data associated with a payment transaction involving a user associated with user device 102 and a merchant associated with merchant system 104. In some non-limiting embodiments or aspects, payment gateway system 106 may receive the payment transaction message from acquirer system 108 based on acquirer system 108 receiving data associated with a payment transaction. For example, acquirer system 108 may transmit the payment transaction message including the data associated with the payment transaction to payment gateway system 106 based on acquirer system 108 receiving the data associated with the payment transaction from merchant system 104. In such an example, acquirer system 108 may generate the payment transaction message. In another example, acquirer system 108 may transmit the payment transaction message including the data associated with the payment transaction to payment gateway system 106 based on (e.g., in response to and/or after) acquirer system 108 receiving the payment transaction message from merchant system 104. In such an example, merchant system 104 may generate the payment transaction message based on merchant system 104 determining the data associated with the payment transaction.

In some non-limiting embodiments or aspects, acquirer system 108 may generate the payment transaction message based on data associated with the payment transaction that acquirer system 108 received from merchant system 104. For example, acquirer system 108 may generate the payment transaction message based on data associated with the payment transaction and a messaging standard (e.g., a template for generating transaction messages, the template defining one or more API fields). In some non-limiting embodiments or aspects, the messaging standard may be associated with the acquirer system 108. In another example, the message standard may be associated with payment gateway system 106 and/or issuer system 112.

As shown in FIG. 3 , at step 304, process 300 may include determining a plurality of application programming interface (API) fields of the payment transaction message. For example, payment gateway system 106 may determine one or more API fields of a payment transaction message based on the data associated with the payment transaction included in the payment transaction message. In such an example, payment gateway system 106 may determine the one or more API fields of the payment transaction message based on acquirer system 108 from which payment gateway system 106 received the payment transaction message. In another example, payment gateway system 106 may determine the one or more API fields of the payment transaction message based on issuer system 112 to which the payment transaction message is addressed. In some non-limiting embodiments or aspects, payment gateway system 106 may determine the one or more API fields of the payment transaction message based on receiving the payment transaction message. For example, payment gateway system 106 may determine the one or more API fields of the payment transaction message based on payment gateway system 106 receiving the payment transaction message from acquirer system 108.

In some non-limiting embodiments or aspects, payment gateway system 106 may determine the one or more API fields of the payment transaction message based on payment gateway system 106 determining that the payment transaction message is associated with a route through an electronic payment processing network. For example, payment gateway system 106 may determine the payment transaction message is associated with the route through the electronic payment processing network based on payment gateway system 106 determining that user device 102 and/or merchant system 104 are involved in the payment transaction. Additionally or alternatively, payment gateway system 106 may determine that the payment transaction message is associated with the route through the electronic payment processing network based on determining that issuer system 112 is involved in the payment transaction. For example, payment gateway system 106 may determine that issuer system 112 is involved in the payment transaction based on payment gateway system 106 determining that a payment account associated with user device 102 (e.g., issued to the user associated with user device 102) is associated with issuer system 112.

In some non-limiting embodiments or aspects, one or more of API fields of the one or more API fields of the payment transaction message may be associated with one or more of an address verification system (AVS) field, a payment installment field, an API field associated with a custom code of one or more systems associated with a route through the electronic payment processing network, and/or other like fields. For example, a first API field of the one or more API fields of the payment transaction message may be an AVS field that corresponds to data associated with an address involved in the payment transaction (e.g., an address associated with user device 102 and/or merchant system 104). In another example, a second API field of the one or more API fields of the payment transaction message may be a payment installment field that corresponds to data associated with a payment installment type (e.g., instructions to transfer funds from an account maintained by issuer system 112 to acquirer system 108 within a predetermined period of time, immediately, and/or the like.

In some non-limiting embodiments or aspects, payment gateway system 106 may determine an API field requirement associated with the payment transaction message. For example, payment gateway system 106 may determine an API field requirement associated with the payment transaction message based on the data associated with the payment transaction included in the payment transaction message. The API field requirement may include, for example, one or more API fields that must be included in a payment transaction message to successfully process the payment transaction message when transmitted along a route through an electronic payment processing network. Additionally or alternatively, payment gateway system 106 may determine the API field requirement associated with the payment transaction message based on one or more previously-processed payment transaction messages. For example, payment gateway system 106 may determine the API field requirement associated with the payment transaction message based on one or more previously-processed payment transaction messages. In such an example, payment gateway system 106 may determine the API field requirement associated with the payment transaction message based on one or more previously-processed payment transaction messages where payment gateway system 106 determines that the route through the electronic payment processing network associated with the one or more previously-processed payment transaction messages is associated with (e.g., is partially and/or completely the same as) the route through the electronic payment processing network associated with the payment transaction message. In some non-limiting embodiments or aspects, payment gateway system 106 may determine the API field requirement associated with the payment transaction message based on payment gateway system 106 determining that the one or more previously-processed payment transaction messages are associated with payment transactions that were successfully processed.

In some non-limiting embodiments or aspects, payment gateway system 106 may compare the API field requirement to the one or more API fields of the payment transaction message. For example, payment gateway system 106 may compare the API field requirement to the one or more API fields of the payment transaction message based on payment gateway system 106 determining the API field requirement associated with the payment transaction message. In some non-limiting embodiments or aspects, payment gateway system 106 may determine one or more of the API fields of the payment transaction message to be modified. For example, payment gateway system 106 may determine that one or more of the API fields of the payment transaction message to be modified based on the API field requirement. In such an example, payment gateway system 106 may compare the one or more API fields of the payment transaction message to the API field requirement and payment gateway system 106 may determine the one or more API fields of the payment transaction message to be modified based on the comparison of the one or more API fields of the payment transaction message to the API field requirement.

In some non-limiting embodiments or aspects, payment gateway system 106 may determine one or more API fields of the payment transaction message to be modified based on an API field requirement associated with a merchant involved in the payment transaction. For example, payment gateway system 106 may determine the one or more API fields of the payment transaction message to be modified based on one or more previously-processed payment transaction messages associated with the merchant. In such an example, payment gateway system 106 may determine the API field requirements associated with the one or more previously-processed payment transaction messages associated with the merchant and payment gateway system 106 may determine one or more API fields of the payment transaction message to be modified based on the API field requirements associated with the one or more previously-processed payment transaction messages.

In some non-limiting embodiments or aspects, payment gateway system 106 may determine one or more API fields of a second payment transaction message. For example, payment gateway system 106 may determine one or more API fields of a second payment transaction message that was previously-received by payment gateway system 106 and/or previously-processed (e.g., received by payment gateway system 106 and transmitted to issuer system 112) by payment gateway system 106. In such an example, the second payment transaction message may be associated with a route through the electronic payment processing network. In some non-limiting embodiments or aspects, the route through the electronic payment processing network associated with the second payment transaction message may be the same as or different to the route through the electronic payment processing network that is associated with the payment transaction message.

In some non-limiting embodiments or aspects, payment gateway system 106 may compare the one or more API fields of the second payment transaction message to the one or more API fields of the payment transaction message. For example, payment gateway system 106 may compare the one or more API fields of the second payment transaction message to the one or more API fields of the payment transaction message based on payment gateway system 106 determining that the second payment transaction message and the payment transaction message are associated with one another (e.g., that the second payment transaction message and the payment transaction message are both associated with the same route through the electronic payment processing network, that the second payment transaction message and the payment transaction message are both associated with merchant system 104, that the second payment transaction message and the payment transaction message are associated with issuer system 112, and/or the like).

In some non-limiting embodiments or aspects, payment gateway system 106 may determine one or more API fields of the payment transaction message to be modified based on comparing the one or more API fields of the second payment transaction message to the one or more API fields of the payment transaction message. For example, payment gateway system 106 may determine that the one or more API fields are included in the second payment transaction message that are not included in the payment transaction message. Payment gateway system 106 may then determine that the one or more API fields that are included in the second payment transaction message are to be included in the API fields of the payment transaction message. In another example, payment gateway system 106 may determine that the one or more API fields of the payment transaction message are not included in the one or more API fields of the second payment transaction message. Payment gateway system 106 may then determine that the one or more fields included in the payment transaction message that are not included in the second payment transaction message are not to be included in the one or more API fields of the payment transaction message.

As shown in FIG. 3 , at step 306, process 300 may include modifying one or more application programming interface (API) fields of the payment transaction message. For example, payment gateway system 106 may modify one or more API fields of the payment transaction message. In such an example, payment gateway system 106 may modify the one or more API fields of the payment transaction message based on payment gateway system 106 determining the one or more API fields of the payment transaction message to be modified.

In some non-limiting embodiments or aspects, payment gateway system 106 may modify one or more API fields of a payment transaction message based on payment gateway system 106 determining that one or more API fields of the payment transaction message are merchant API fields that are associated with a merchant. For example, payment gateway system 106 may modify the one or more API fields of a payment transaction message based on payment gateway system 106 determining that the one or more API fields of the payment transaction message are merchant API fields associated with a merchant. In such an example, the merchant API fields may correspond to data associated with the payment transaction and/or data generated by merchant system 104 that is associated with the payment transaction. In some non-limiting embodiments or aspects, payment gateway system 106 may generate a modified payment transaction message based on modifying the one or more API fields of the payment transaction message.

In some non-limiting embodiments or aspects, payment gateway system 106 may modify one or more API fields of the payment transaction message by payment gateway system 106 including one or more API fields in the payment transaction message. For example, payment gateway system 106 may modify one or more API fields of the payment transaction message by payment gateway system 106 including one or more API fields in the payment transaction message, the one or more API fields including default values (e.g., default values for a payment transaction). In an example, payment gateway system 106 may modify one or more API fields of the payment transaction message by payment gateway system 106 including one or more API fields in the payment transaction message, the one or more API fields including values generated by payment gateway system 106 based on the data associated with the payment transaction. In some non-limiting embodiments or aspects, payment gateway system 106 may modify the one or more API fields of the payment transaction message based on one or more trends and/or the date on which the payment transaction was initiated. For example, payment gateway system 106 may modify the one or more API fields of the payment transaction message based on a trend that one or more parameters of the payment transactions be included in payment transaction messages when processing the payment transactions. In another example, payment gateway system 106 may modify the one or more API fields of the payment transaction message based on the date where one or more API fields are requested during a particular date or range of dates (e.g., one or more API fields may be requested during a period of time associated with a holiday and/or the like).

In some non-limiting embodiments or aspects, payment gateway system 106 may modify the one or more API fields of the payment transaction message independent of modifying a payload of the payment transaction message (e.g., data included in the payment transaction message such as the data associated with the payment transaction and/or other data included in the payment transaction message). For example, payment gateway system 106 may modify the one or more API fields of the payment transaction message and payment gateway system 106 may modify the payload of the payment transaction message based on modifying the one or more API fields of the payment transaction message. In another example, payment gateway system 106 may modify the payload of the payment transaction message before modifying the one or more API fields of the payment transaction message. In an example, payment gateway system 106 may modify the one or more API fields of the payment transaction message and payment gateway system 106 may forego modifying the payload of the payment transaction message.

As shown in FIG. 3 , at step 308, process 300 may include transmitting the modified payment transaction message. For example, payment gateway system 106 may transmit the modified payment transaction message to issuer system 112. In such an example, payment gateway system 106 may transmit the modified payment transaction message based on payment gateway system 106 modifying the one or more API fields of the payment transaction message. Payment gateway system 106 may transmit the modified payment transaction message to issuer system 112 along a route through the electronic payment processing network. In some non-limiting embodiments or aspects, the route through the electronic payment processing network may be the same as the route associated with the payment transaction message. Additionally or alternatively, payment gateway system 106 may transmit the modified payment transaction message along a route that is different from the route associated with the payment transaction message (e.g., a route associated with a previously-processed payment transaction message, a route associated with merchant system 104 involved in the payment transaction, a route associated with the issuer system 112 involved in the payment transaction, and/or the like).

FIGS. 4A-4G are an overview of a non-limiting embodiment or aspect of an implementation 400 for updating an API field of a transaction message. As shown in FIGS. 4A-4G, implementation 400 may include payment gateway system 406, acquirer system 408, issuer system 412, and payment processing node 416. In some non-limiting embodiments or aspects, payment gateway system 406 may be the same or similar to payment gateway system 106. In some non-limiting embodiments or aspects, acquirer system 408 may be the same or similar to acquirer system 108.

Payment processing node 416 may include one or more computing devices configured to be in communication with payment gateway system 406, acquirer system 408, and/or issuer system 412 via a communication network (e.g., communication network 114 and/or a communication network that is the same as or similar to communication network 114). For example, payment processing node 416 may include a server, a group of servers, and/or other like devices. In some non-limiting embodiments or aspects, payment processing node 416 may be associated with a payment gateway, a transaction service provider, a merchant, an acquirer, an issuer, and/or the like as described herein.

As shown by reference number 420 in FIG. 4A, payment gateway system 406 may receive a first payment transaction message from acquirer system 408. For example, payment gateway system 406 may receive the first payment transaction message from acquirer system 408 based on acquirer system 408 receiving data associated with a payment transaction. In such an example, payment gateway system 406 may receive the first payment transaction message from acquirer system 408 based on acquirer system 408 receiving data associated with a payment transaction from a merchant system (e.g., merchant system 104) after the merchant system communicates with a user device (e.g., user device 102) to initiate the payment transaction.

As shown by reference number 425 in FIG. 4A, payment gateway system 406 may determine a plurality of API fields. For example, payment gateway system 406 may determine a plurality of API fields of the first payment transaction message. In such an example, payment gateway system 406 may determine the plurality of API fields of the first payment transaction message where the first payment transaction message is associated with a first route through an electronic payment processing network.

As shown by reference number 430 in FIG. 4B, payment gateway system 406 may transmit a first payment transaction message to issuer system 412. For example, payment gateway system 406 may transmit a first payment transaction message to issuer system 412 via a first route through the electronic payment processing network (e.g., from payment gateway system 406 to issuer system 412). In such an example, payment gateway system 406 may forego transmitting the first payment transaction message to issuer system 412 via a different route (e.g., a second route from payment gateway system 406 to issuer system 412 via payment processing node 416).

As shown by reference number 435 in FIG. 4C, payment gateway system 406 may receive a second payment transaction message from acquirer system 408. For example, payment gateway system 406 may receive a second payment transaction message from acquirer system 408 based on acquirer system 408 receiving data associated with the second payment transaction different from the payment transaction associated with the first payment transaction message. In such an example, payment gateway system 406 may receive the second payment transaction message from acquirer system 408 based on acquirer system 408 receiving data associated with the second payment transaction from a merchant system (e.g., merchant system 104 and/or a different merchant system) after the merchant system communicates with a user device (e.g., user device 102 and/or a different user device) to initiate the second payment transaction.

As shown by reference number 440 in FIG. 4C, payment gateway system 406 may determine a plurality of API fields. For example, payment gateway system 406 may determine a plurality of API fields of the second payment transaction message. In such an example, payment gateway system 406 may determine the plurality of API fields of the second payment transaction message where the second payment transaction message is associated with a second route through the electronic payment processing network.

As shown by reference number 445 in FIG. 4D, payment gateway system 406 may compare the plurality of API fields of the first payment transaction message to the plurality of API fields of the second payment transaction message. For example, payment gateway system 406 may compare the one or more API fields of the first payment transaction message to the one or more API fields of the second payment transaction message and payment gateway system 406 may determine that one or more API fields of the first payment transaction message are associated with and/or are not associated with one or more API fields of the second payment transaction message.

As shown by reference number 450 in FIG. 4E, payment gateway system 406 may determine one or more API fields to be modified. For example, payment gateway system 406 may determine one or more API fields to modify of the second payment transaction message based on comparing the plurality of API fields of the first payment transaction message to the plurality of API fields of the second payment transaction message.

As shown by reference number 455 in FIG. 4F, payment gateway system 406 may modify one or more API fields of the second payment transaction message. For example, payment gateway system 406 may modify the one or more API fields of the second payment transaction message based on payment gateway system 406 determining the one or more fields of the second payment transaction message to modify. In some non-limiting embodiments or aspects, payment gateway system 406 may include and/or remove an API field from the second payment transaction message. For example, payment gateway system 406 may include an API field in the second payment transaction message that is the same as or similar to an API field included in the first payment transaction message. In an example where payment gateway system 406 includes the API field in the second payment transaction, payment gateway system 406 may determine a value associated with the API field that was included in the second payment transaction message, the value determined based on the data associated with the payment transaction of the second payment transaction message and/or a default value. In some non-limiting embodiments or aspects, payment gateway system 406 may receive input (e.g., at payment gateway system 406) representing one or more new mandates (e.g., one or more API fields) that are to be included or not included in payment transaction messages transmitted along one or more routes of the electronic payment processing network.

As shown by reference number 460 in FIG. 4G, payment gateway system 406 may transmit the modified second payment transaction message. For example, payment gateway system 406 may transmit the modified second payment transaction message via the first route through the electronic payment processing network. In such an example, payment gateway system 406 may transmit the modified second payment transaction message via the first route through the electronic payment processing network based on payment gateway system 406 modifying the second payment transaction message. In some non-limiting embodiments or aspects, after payment gateway system 406 modifies the payment transaction message, payment gateway system 406 may transmit the modified second payment transaction message via the second route through the payment processing network. In some non-limiting embodiments or aspects, payment gateway system 406 may transmit the second payment transaction message along the first route or the second route through the electronic payment processing network based on payment gateway system 406 determining that the first route or the second route through the electronic payment processing network is associated with a higher success rate for processing payment transactions. For example, payment gateway system 406 may transmit the second payment transaction message along the first route or the second route through the electronic payment processing network based on payment gateway system 406 determining that the first route or the second route through the electronic payment processing network is associated with a higher success rate for processing payment transactions based on payment gateway system 406 determining that one or more payment transaction messages were successfully processed when transmitted along the first route and the second route through the electronic payment processing network.

In some non-limiting embodiments or aspects, payment gateway system 406 may generate a message including data associated with the modification of the second payment transaction message and payment gateway system 406 may transmit the message to acquirer system 408. Acquirer system 408 may then modify one or more payment transaction messages generated after the second payment transaction message was generated based on the modification of the second payment transaction message.
